There are many illustrations in my Digital Myst Book project, and I've decided to provide at least the maps as a separate download, mostly because there aren't lots of good Myst maps out there.
Here is the Temple Island Map from Riven I drew for my Digital Myst Book project. If you want to use it, please tell me about it at email@example.com
The map is in JPG format and is drawn by hand on a computer, using a Wacom Cintiq 21UX. The format is 1000x722 pixels and is meant for web use. If you want a bigger map (2928x2113) with transparencies and in layers for some print job, contact me and we'll see what we can do.
So, again - free to use for personal use, but please let me know what you use it for and I'll even include you on this page. Click the image above for a larger version that you can drag to your desktop.
